8 * The C99 types uintXX_t that are usually defined in 'stdint.h' are not as
9 * unambiguous on ARM as you would expect. For the types below, there is a
10 * difference on ARM between GCC built for bare metal ARM, GCC built for glibc
11 * and the kernel itself, which results in build errors if you try to build with
12 * -ffreestanding and include 'stdint.h' (such as when you include 'arm_neon.h'
13 * in order to use NEON intrinsics)
15 * As the typedefs for these types in 'stdint.h' are based on builtin defines
16 * supplied by GCC, we can tweak these to align with the kernel's idea of those
17 * types, so 'linux/types.h' and 'stdint.h' can be safely included from the same
18 * source file (provided that -ffreestanding is used).
20 * int32_t uint32_t uintptr_t
21 * bare metal GCC long unsigned long unsigned int
22 * glibc GCC int unsigned int unsigned int
23 * kernel int unsigned int unsigned long
